**1. Write three paragraphs to define the term 'ergonomics'. (3 paragraphs)**
Ergonomics focuses on the workers and their environment in order to create something that improves the workers’ performance. For example, designing a chair that takes the form of a person’s body in order to comfort them for long periods of time. An ergonomic workplace makes workers comfortable since there regular tasks are done in an effective, or the right way.

Ergonomics plays a critical part in improving workers productivity by making them feel less stressed, comfortable and full of energy. Ergonomics tries to create objects for workers in the workplace that improve human practices, or allow them to perform their tasks easily. If a workplace is designed ergonomically, workers would be safer because they would not have many injuries. For example, having a strain in your wrists because you were typing for a long time in a non-ergonomic way.

Motion study is like ergonomics because it analyzes the motion used by workers in the workplace to find the best method for the way of doing things in the workplace. Frank Therblig used motion study to find the best way for brick layering that makes workers' job easier which will make them more productive in their work.

**2. What is the 'Gilbreth system of motion analysis' (1 paragraph)**
The ‘Gilbreth system of motion analysis’ allows you to study the motion percentage in a certain activity. It was applied to brick layering in an effort to improve how brick layering was done. The 'Gilbreth system of motion analysis' analyzes motion performed by workers. In the case of brick layering, it analyzes the motion per brick of a worker that is brick layering. It gave Gilbreth an idea about the amount of motion that is used in the brick layering task which helped him create something that reduces the amount of motion used by the workers in order to save their energy. Saving workers energy can make workers more productive.

**3. Who was Frank Therblig, and how did he utilize 'motion study'? (2 paragraphs)**
Frank Therblig tried to figure out the possible methods of layering bricks. Therblig got interested in finding the best and most effective method of layering bricks. This investigation led him to create motion study. The traditional way of brick layering was ineffective, stressful and messy.

Motion study was applied to brick layering in an effort to finding the best method for layering bricks. Motion study was used on a single man that was stooping bricks. Therblig found out that the man used more energy bending down to get the brick than moving the actual brick. Motion study gave different rates of motions per brick by allowing Therblig to find the best method that does not let the man use a lot of energy while he is layering bricks. This analysis made brick layering workers more productive by reducing their energy per brick.

**4. Describe three categories Frank Gerblith used in the Therblig Analysis Checklist. (3 paragraphs)**
The three categories that I chose to describe from Frank Gerblith's Therblig Analysis Checklist are the following:

-This category of Frank Gerblith's Therblig Analysis Checklist analyzes the workers' movement in different tasks. Some of the questions focus on transportation of materials during a task. This category can help figure out an effective method for moving things.
 * 1. Reach and Move**

-This category of Frank Gerblith's Therblig Analysis Checklist analyzes the task of searching. It includes questions about things that affect the searching task. This category can help figure out an effective method for searching for materials and other things that a worker needs to carry out their task.
 * 2. Search**

-This category of Frank Gerblith's Therblig Analysis Checklist analyzes the resting condition of, and the energy used by workers/ operators during their work. Some of the questions in this category focus on working conditions, operators' weight, the bench height and does the operator feel comfortable with what is available to them during their work. There was a question that analyzes the operators' nutrition. This category can help figure out an effective method that can effectively use the workers' energies in their given tasks.
 * 3. Rest to Overcome Fatigue**
